Test points are small metallic pins on the optional feedback module.
Hardware troubleshooting and testing for proper wiring can begin by
testing for proper voltage or signals at these pins.
Test points are labeled with the letters TP followed by a number.
Figure 4B.22 shows the location of each test point and lists the test data of
each test point.

The test points of the optional feedback module can monitor the feedback
signals from one feedback port on the servo module and/or one feedback
port on the optional feedback module at one time. A rotary switch on the
optional feedback module allows the selection of which ports the test
points are monitoring. Table 4B.G lists the rotary switch positions and the
corresponding ports the test points monitor at each switch position.
